The Jasna Góra Monastery in Częstochowa

Truly a remarkable place of pilgrimage, this monastery houses the revered Black Madonna painting (below is a reproduction within the monastery; we walked on our knees on a well-rutted trail past the original icon during a Mass service so I did not want to take a picture although it was possible).

If you appreciate sacred spaces no matter the religion this place is among the most profound you can ever visit.
